DUO-VIS biopolymer viscosifier is a dispersible, non clarified, high-molecular-weight biopolymer used for increasing viscosity in water-based drilling fluid systems.

Small quantities provide viscosity and weight material suspension for all water-based mud systems. DUO-VIS biopolymer has the unique ability to produce a fluid that is highly shear-thinning and thixotropic.

The primary function of DUO-VIS biopolymer is to increase viscosity for cuttings transport and suspension. It performs effectively in all water-based fluids, ranging from highly weighted to low-solids systems. This includes freshwater, seawater, salt, and heavy brine fluid systems.
